The above forces are both applied to the bearing journal and bearing bush, and the resultant force on the stator through the bush is equal and opposite to the load applied to the rotor through the journal.
Therefore the analysis doesn’t include any constraints on the displacement in the bearing journal.
It is possible to develop bearing’s displacement-load relationship with three-moment methods: li-1Mi-1Ei-1Ii-1+2Mili-1Ei-1Ii-1+liEiIi+liMi+1EiIi-6zi-1li-1+6zi1li-1+1li-6zi+1li=-14qi-1li-13Ei-1Ii-1+qili3EiIi (6) where li, Mi, Ei, qi are respectively the distance, material young's modulus, section moment of inertia, and equally distributed load of the shaft between i and i+1 bearing, Mi is the bending moment at the i bearing section, zi is the deflection in i section(i is the order of bearing).
Material parameters are: E=211GNm2，G=81.2GNm2，ρ=7810kgm3.

At the same time, austenitic stainless steel is also has the most grades[1-2]. 304 stainless steel is stainless steel material which is commonly used, and it is produced based on the American Society for testing and materials R & D, and is the same with the steel for 0Crl8Ni9 steel in China.
The tensile strength is the material deformation reached the maximum size of the stress, and it is the main basis to judge material.

Introduction Blending of existing polymers is an interesting route towards the development of new polymeric materials [1].
In recent years molecular modeling is gaining acceptance as a reliable technique to analyze the miscibility behavior of polymer materials [3],[4].
These two parameters, CED and δ, are used to predict solubility particularly for non-polar materials such as polymers.

Several works have been done improving the sensitivity of polymer-based AFB1 sensors using doping materials [9-12].
However, molecular imprinting polymer (MIP) is still a new method, and polyvinyl acetate (PVAc) material processed by MIP has not been reported.
